Jarvis Jenkins says he has a torn ACL

The Washington Redskins' feel-good preseason took a big hit Friday morning when rookie defensive end Jarvis Jenkins revealed that he tore the ACL in his right knee during Thursday night's game against Baltimore. It's almost certainly a season-ending injury, though the team has yet to many any announcements about that.

The Redskins' second-round pick in this year's draft, Jenkins injured the knee chasing after Ray Rice early in Thursday night's game. An MRI on Friday morning apparently revealed the severity of the injury. It's a tough blow for Jenkins, who'd played well enough in training camp to challenge for a starting role on the line or at least a prominent role in the team's rotation of defensive ends. He's earned praise for his athleticism and the speed with which he was learning Jim Haslett's defensive schemes.

It's also a tough blow for the Redskins, who were counting on Jenkins to rotate in with Adam Carriker and Stephen Bowen at those end spots and now will have to rely more than they planned on Kedric Golston and others. The Redskins' defense has been one of the most impressive aspects of the team's encouraging preseason performance, and now they're thinner in a key spot.

We say it all the time, but it doesn't matter who wins or loses in preseason, or really how well anyone plays, as long as no one gets seriously hurt. Count the Redskins among the unfortunate teams who couldn't make it through the preseason without a significant injury.
